How to configure Single Sign-On for HubSpot?

HubSpot is one of the most widely used tools for marketing, sales, and customer engagement. Teams depend on it every day, which makes securing access a top priority. Relying on separate usernames and passwords creates risks like weak credentials, forgotten logins, or the hassle of managing multiple accounts. That’s where HubSpot SSO (Single Sign-On) comes in.

With HubSpot single sign on, employees only need one login through a trusted identity provider (IdP). Once authenticated, they can jump into HubSpot and other connected apps without typing different usernames or passwords each time. For IT teams, it means stronger security, simpler management, and fewer support tickets about lost passwords.

In this guide, we’ll show you why single sign-on (SSO) matters for HubSpot and how to complete a HubSpot SSO setup using Scalefusion OneIdP. By the end, you’ll know how to enable HubSpot login with SSO and create a smoother, more secure experience for your entire organization.

Why enable SSO for HubSpot?

HubSpot has become a central platform for running campaigns, managing contacts, and analyzing performance. But with so many people accessing it from different devices and locations, security becomes a concern.

Enabling HubSpot SSO is the easiest way to balance security with convenience. It not only reduces the chance of weak or reused passwords but also gives IT full control over who can access HubSpot.

Key benefits of enabling HubSpot Single Sign On

• Stronger authentication: Instead of relying on standalone passwords, employees use a centralized identity system. This ensures that HubSpot login with SSO is backed by company security policies like MFA or device checks.
• Faster and simpler access: Users skip the long list of credentials and go straight to their dashboard with HubSpot sign in with SSO.
• Easier onboarding and offboarding: When someone joins or leaves the company, their access to HubSpot can be added or revoked instantly through the IdP.

In short, sign in with SSO HubSpot makes life easier for both employees and IT teams, while tightening security at the same time.

Step-by-step guide: Configure SSO for HubSpot

Ready to begin your HubSpot SSO setup? Follow these steps to connect HubSpot with Scalefusion OneIdP.

Prerequisites for HubSpot SSO Setup

Before you start, make sure these checks are complete:

• The custom domain you plan to authorize is verified through OneIdP.
• Users belonging to the custom domain are added to the Scalefusion Dashboard and migrated to OneIdP.
• IT admins have access to the HubSpot Admin Console.
• Users are already added to the HubSpot portal.

Once you have completed these steps, you’re ready to setup HubSpot SSO.

Here’s a visual interactive demo of the set up process.

Now let us walk through the process of setting up Hubspot SSO using Scalefusion OneIdP.

Step 1: Create SSO in Scalefusion

1. Log in to Scalefusion Dashboard → go to OneIdP > SSO Configuration.

2. Click the New SSO Configuration button on the top right.

3. After clicking New SSO Configuration, a window will appear. Search for HubSpot in the list, select it, and then click Configure.

4. This opens a setup wizard with 6 tabs:

• Application Basics
• SSO Scope Management
• Permissions
• SSO Settings
• Conditional Access
• User Facing Messages

Navigate to each tab and enter the required details. You can navigate to the next tab only after you have entered the complete details in the current section. 

5. Once you have entered all details click Next

Step 2: Configure SSO in HubSpot

1. In the HubSpot Admin Console, click the gear icon in the upper-right corner of the page.

2.  Click on Account Defaults

3. Scroll to Security > Set up Single Sign-On.

4. Copy these details from Scalefusion dashboard and paste in respective boxes.

• Entity ID/Issuer URL → Identity Provider Identifier
• SSO URL → Identity Provider Sign-On URL
• X.509 Certificate → Paste the certificate from Scalefusion metadata

5. Click Verify.

6. Under Single Sign-On, check Require SSO to log in if you want all users to only log in via SSO.

Step 3: Apply Conditional Access (Optional but recommended)

Device Policy

• Allow only Scalefusion-managed devices.
• Or allow both, but ask for OTP if the device is unmanaged.
• Or enforce MFA/OTP if enabled in Directory Settings.
• Optionally, skip password entry on managed devices (except ChromeOS).

Browser Policy

• Allow all browsers (default), or restrict to specific browsers (Chrome, Edge, Safari, Firefox) with minimum version requirements.

Access Exceptions

• Enrollment Exceptions: Let new users access HubSpot temporarily before enrolling a device, with session and OS limits.
• User Exceptions: Exempt specific users from device/browser rules while still requiring OneIdP login.

Step 4: Customize User Messages

Set clear instructions for users if access is blocked due to:

• Non-compliant device
• Unsupported browser
• Access denied

Step 5: Save and Test

1. Click Save in Scalefusion.

2. Test the setup:

• Go to your HubSpot Login URL
• Here your Login Link will redirect you to OneIdP page to authenticate.
• After entering credentials, click on Sign In.

• You should be logged in into HubSpot.

Done! Your HubSpot is now secured with OneIdP SSO, and you can control access with device, browser, and user-based rules.
